Title: An automatic machine for moulding blocks and tiles for walls, floors, roofs and the like
IPC: B28B5/02
Filed: 1924-03-31
Abstract: 237,635. Wikkula, V. March 31, 1924. Endless-chain machines; feeding. - In automatic tile &c. machines of the type in which the mould chain passes over polygonal wheels, the central portion of the chain is supported upon a table which is given a tilting movement corresponding to the rise and fall of the chain as it passes over the angular corners of the wheels. The table M, Fig. 2, is pivoted upon a horizontal shaft H and is supported at the end by supports M<1> carrying rollers which engage with eccentrics F, Fig. 4, which impart a tilting movement to the table corresponding to the movements of the chain as it passes over the polygonal wheels D. Plastic material is supplied to the moulds in layers by two moving containers k, i, and a stationary container h prior to passing below a press l. The containers k, i are moved transversely across the moulds when the chain is stationary by a lever o, Fig. 4, operated by a pin n carried by gear wheels m, and are returned by a counterpoise r. The container i may be divided by partitions if it is desired to have more than three layers of material in the tiles. The stationary container h is provided with a roller a rotated by belt pulleys at the bottom to prevent stones or other coarse particles from getting between the lower edge of the container and the walls g of the moulds. The press l is operated by bell-crank levers t on both sides of the machine, and simultaneously wedgeshaped side members u, Fig. 4, move down to force side presses v to compress the sides of the tile into the desired shape. The completed tiles are discharged from the moulds by a lever B operating through holes in the chain. The loose sole plates, upon which the layers of material are spread, are placed upon the chain at D<1>. The chain is intermittently moved by the ratchet mechanism e<2>, e<3> operated by a rotating arm e.

Abstract: The invention comprises 2 : 6-bis-aziridino-1 : 4 - benzhydroquinone, 2 : 6 - bis - aziridinobenzoquinone and 2 : 3 : 6-tris-aziridino-1 : 4-benzoquinone.  2 : 6-Bis-aziridino-1 : 4-benzhydroquinone and 2 : 3 : 6 - tris - aziridino - 1 : 4-benzoquinone are made by reacting a 2 : 6-dialkoxy-1 : 4-benzoquinone, in which the alkyl groups preferably have 1-4 carbon atoms, with an excess of aziridine, at or below room temperature and preferably below 0 DEG  C., under anaerobic conditions, e.g. in an atmosphere of nitrogen, in an inert diluent such as an alkanol of 1-4 carbon atoms, e.g. methanol, and subsequently separating the two reaction products, for example by leaching out the soluble 2 : 3 : 6-tris-aziridino-benzoquinone with cold acetone, benzene or chloroform to leave a residue of 2 : 6 - bis - aziridino - 1 : 4 - benzhydroquinone.  2 : 6 - Bis - aziridino - benzoquinone is made by oxidizing 2 : 6-bis-aziridino-1 : 4-benzhydroquinone, suitably by treatment with p-benzoquinone in an aqueous, organic or aqueous organic reaction medium.  In examples: (1) 2 : 6 - dimethoxy - 1 : 4 - benzoquinone is treated with aziridine in methanol, the precipitated product is extracted with benzene to leave a residue of 2 : 6-bis-aziridino-2 - 4-benzhydroquinone (recrystallized from dioxane) and a solution of 2 : 3 : 5-tris-aziridino-1 : 4-benzoquinone (recrystallized from ethyl acetate) and (2) the bis-aziridino compound from (1) is oxidized with p-benzoquinone to give 2 : 6-bis-aziridino-1 : 4-benzoquinone.

Title: Improved dyeing process
Inventor: KENNEDY JOHN GEORGE
IPC: D06P1/12
Filed: 1957-03-14
Abstract: Textile fabrics composed of fibres which will dye with a diazotizable dispersed acetate dye, are treated with a diazotizable dye, diazotized, water-washed, and then treated with a buffer solution comprising a weak organic acid and a salt of a p  weak organic acid, either immediately prior to, or in conjunction with, coupling the diazotized dye with phloroglucinol, and any part-coupling treatment is effected in the coupling bath.  Fabrics of cellulose acetate and triacetate and polyamides may be treated in this way, and diazotizable cellulose acetate disperse dyes are preferred.  The buffer solution may comprise acetic acid and sodium acetate.  The coupling bath may contain conventional additives, e.g. sodium sulphate and dispersing agents, and part-coupling treatment, effected in the coupling bath, may include soaping off.  In an example, an acetate fabric is dyed with Dispersol Diazo Black 2BS (C.I. Disperse Black 2), diazotized, water-washed and then treated for 5 minutes at 20 DEG  C. in a bath containing 60 gms. sodium acetate and 60 mls. 30% by weight acetic acid in 60 litres of water.  Coupling was effected by adding 10 gms. phloroglucinol and heating to 30 DEG  C. After 15-30 mins. the temperature was raised to 50 DEG  C.  The bath was then neutralized with ammonia, 20 gms. soap added and the temperature held at 50-70 DEG  C. for 15 mins., after which the fabric was rinsed and dried.  A black dyed fabric of good penetration and fastness was obtained.

Title: Improvements in or relating to concentration or absorption towers
IPC: B01D3/20
Filed: 1934-03-19
Abstract: <PICT:0435134/III/1> <PICT:0435134/III/2> <PICT:0435134/III/3> Towers for the concentration of liquids by evaporation or absorption contain a number of transverse members each having one or more openings 11 provided with orifices or notches 15.  The liquid to be concentrated is fed on to the top member through openings 5 and 6 and then flows through the orifices 15 and falls in the form of an annular curtain of liquid on the member below, passing in a similar manner from member to member to the bottom of the tower.  Hot gases admitted through pipes 10 and 10<a> pass up the tower through the apertures 11 and are forced to pass in succession through the curtains of liquid. The hot gases may alternatively pass down the tower and may be generated by burners in the tower.  The latter may be built up from the members as shown or alternatively the members may be secured in a tower already constructed.  The liquid from orifices 15 may fall on intermediate members 13 and flow over the outer edges of these on to the apertured members below.  Projections 16 may be provided beneath the orifices 15 to prevent the liquid streams forming the annular curtain from coalescing.

A pin 22 interconnects the pawls 16 which as shown are four in number. The spring-loading for both the pawls and the handle member is a single spring which has two coiled sections 25 interconnected by a loop 26 the outer end portions 28 of the spring being substantially straight. The spring surrounds the pin 22 and the end portions 28 engage the handle member and the loop 26 engages underneath a shoulder 27 of a member 17 which surrounds the shaft 11 and has a slot 24 to permit movement of the pin 22, the ends of which are connected to the handle. The member 17 has a tongue and slot connection with the channel shaped member and so cannot move when the handle is moved. One end section of the belt passes round a member 10 which is slidably mounted by means of a pin 9 in an opening of the channel-shaped member so that the end of the belt section is gripped between the member 10 and an edge of the opening.

Sodium ethoxide is the preferred condensing agent.  The products may be isolated as free bases or salts.  In the examples, the following 3 - aminopyrazolines (or 3 - iminopyrazolidines) are obtained: 1-phenyl, 1-o-, m- and p-tolyl, 1 - p - methoxyphenyl, 1 - p - acetaminophenyl, 1-phenyl-4- and 5-methyl, 1 : 5-diphenyl and 1-m- and p-tolyl-5-phenyl, as well as 3-aminopyrazoline itself (isolated as hydrochloride).
